agent-session-viewer 0.3.1

A web viewer for AI agent coding sessions (Claude Code, Codex, etc.)

Agent Session Viewer

Browse, search, and revisit your AI coding sessions. Never lose track of that clever solution your AI pair programmer came up with three weeks ago.

Why?

AI coding sessions pile up fast. Finding that one conversation where you solved a tricky bug or implemented a specific pattern means digging through session files by hand. This tool gives you instant full-text search across every session from Claude Code and Codex, organized by project.

Features

• Full-text search - Find any message across all your sessions instantly
• Live updates - Active sessions refresh automatically as new messages arrive
• Auto-sync - Background sync every 15 minutes, plus manual sync with r
• Keyboard-first - Vim-style navigation (j/k/[/]) for fast browsing
• Project organization - Sessions grouped by codebase
• Export & publish - Download sessions as HTML or publish to GitHub Gist for sharing
• Local-first - All data stays on your machine in ~/.agent-session-viewer/
• Zero config - Works out of the box

Keyboard Shortcuts

Key	Action
j / k	Next / previous message
] / [	Next / previous session
o	Toggle message order
r	Sync sessions
e	Export session as HTML
p	Publish session to Gist
⌘K	Focus search
?	Show all shortcuts

Export & Publish

Share your AI coding sessions with teammates, for blog posts, or to document how you solved a problem.

Export to HTML

Press e or click Export to download the current session as a self-contained HTML file.

• Works offline in any browser
• Interactive toggles for thinking blocks and message order (pure CSS, no JavaScript)
• Can be hosted on any static file server or shared directly

Publish to GitHub Gist

Press p or click Publish to instantly share a session via GitHub Gist.

First-time setup:

1. Click "Publish" — a setup modal appears
2. Click the link to create a GitHub token (only needs the gist scope)
3. Paste the token and click "Save Token"

After setup, publishing is one click. You'll get two URLs:

URL	Purpose
View URL	Shareable link that renders the HTML directly in the browser
Gist URL	Link to the gist on GitHub (for editing or deleting)

Your token is stored locally in ~/.agent-session-viewer/config.json with restricted file permissions.

Supported Agents

• Claude Code - syncs from ~/.claude/projects/
• Codex - syncs from ~/.codex/sessions/

How It Works

The viewer syncs sessions from each agent's local storage into its own database with full-text search indexing. When you're viewing an active session, it watches the source file and updates the UI within seconds of new messages.
